Upon the enactment of any bill by the Council, with the exception of such measures made expressly exempt from the executive veto by this Charter, it shall be presented to the County Executive within ten days for their approval or disapproval. Within ten days after such presentation, they shall return any such bill to the Council with their approval endorsed thereon or with a statement, in writing, of their reasons for not approving the same. Upon approval by the County Executive, any such bill shall become law. Upon veto by the County Executive, their veto message shall be entered in the Journal of the Council, and, not later than at its next legislative session-day, the Council may reconsider the bill. If, upon reconsideration, two-thirds of the members of the full Council vote in the affirmative, the bill shall become law. Whenever the County Executive shall fail to return any such bill within ten days after the date of its presentation to them, the Clerk of the Council shall forthwith record the fact of such failure in the Journal, and such bill shall thereupon become law. In the case of budget and appropriation bills, the County Executive may disapprove or reduce individual items in such bills, except where precluded by State law. Each item or items not disapproved or reduced in a budget and appropriation bill shall become law, and each item or items disapproved or reduced in a budget and appropriation bill shall be subject to the same procedure as any other bill vetoed by the County Executive.
